To all whom z't may concern: 7 I

Be it known that I, MIcHAEn SIfORLEDER, a citizen of the United States,residing at Colorado City, in the county of Pas'o and State of Colorado,have invented certain new and useful Improvements in Watches,-

of which the following is a specification.

My invention relates to improvements in watches or time pieces, and hasspecial ref erence to improvements in the means or 'devices forconnecting the hair spring with the balance cook or bridge.

The aim of the invention is the provision of means for connecting thestud er the hair spring with the balance cook or bridge, such meansbeing of the simplest and cheapest possible construction and permittinginstant application or detachment of 'the spring from the balance cockor bridge, as may be found necessary. Another object of my invention isthe provision of devices for'co'nnecting the stud of the hair springwith the balance cock or bridge, which means will under all conditionsretain the spring in proper adjustment, which will be capable ofadllu'sting. the tension of the spring if desired, and

which in general will appeal to persons skilled in the art as presentinga thoroughly eflicient and practical improvement of this character fromevery point of view.

With the attainment of these objects in view, my invention consists inmeans of the character and for the purpose stated embodying novelfeatures of construction and combination of parts, substantially asdisclosed herein.

In order that the detailed construction of my invention and itsapplication and operation may be fully understood as well as itsnumerous advantages be thoroughly appreciated, I have illustrated in theaccompanying drawings various embodiments of my invention and for afuller understanding of my improvements I invite attention to suchdrawings.

Figure 1 represents a perspective view of a balance cook or bridgeequipped with my improvement. Fig. 2 represents a sectional view toillustrate the location of my improvements when in operative position.Fig. 3 represents a perspective view of a modified construction of myinvention. Figs. 4 and 5 represent, respectively, a perspective view anda top plan view of another modified construction of my invention, andFig. 6

representsa detail view of this modified construction of stud fasteningmeans.

In 'the several views of the drawings, I have illustrated a series ofconstructions of devices for -connecting the hair spring with thebalance cock or bridge, all of which constructions embody the same broador generic construction, and in said drawings, the numeral 1 Idesignates the balance book or bridge of the form and constructionusually empldyed in watches at time fpieces,

and in the construction shown in Figs. 1

and 2 the bridge is formed upon one side with a hug '2, havin its lowersurface 3 disposed horizontally and having its 'upper face formed withthe flat horizontal portion 4, and the contiguous channel or 'kerf 5,and the lug is provided with a smooth opening or passage (3.

The hair spring 7 carries the stud 8, which is as shown in 'Figs. 1 and'2, of rounded form upon one surface, and with this stud engages thesimilarly curved hook 9, which is formed with the shank 10 smooth for aproper distance and terminating in the threaded end 11, the smooth shankpassing through the opening 6 and the projected threaded portion 11receiving a milled nut 12 which serves to secure the hook and inconsequence the stud of the hair spring in proper place as Well aspermitting the instant release of the stud when found necessary, thehook being retained by means of a pin 13 abutting the hook.

From this construction it will be observed that it is simply necessaryto place the stud to which the hair spring is connected in the channelor kerf of the bridge or cook and apply the hook to the stud which isthen tightened upon the stud by means of the nut, and to remove the hairspring it is simply necessary to release the adjusting nut which removesthe hook from contact with the stud and permits instant release.

In the form of my invention shown in Fig. 3 I provide in place of thesingle lug a pair of parallel disposed lugs 13 between which the hook 14is mounted and receives the securing pin 15 and in other respects theconstruction is identical with that shown in Figs. 1 and 2. In themodified form of the invention shown in Figs. 4, 5 and 6, the samegeneral construction is employed except that the stud holding hook isformed with a shoulder 16 with which when the hook is in positionbetween the pair of ears or lugs 18 the securing pin 19 engages forretain ing the hook in proper position between said ears or lugs.

From the foregoing description taken in connection with the drawings,the invention will be readily understood by all skilled in the art andconversant with improvements of this character, and it will be at onceapparent that I provide a simple, inexpensive and durable means whichwill absolutely retain the stud of the hair spring in its proper place;which means can be adjusted to suit circumstances and will permit ofinstant application or removal of the stud,

and which means will be of ornamental and attractive appearance and tendto embellish the appearance of the movement and will add practicallynothing to the cost of the balance cock or bridge, while greatly enhancing its efficiency, desirability and use fulness.

I claim 1. In combination with the balance cock or bridge of a watch ortimepiece, a hook carried by said balance cock or bridge, and a hairspring having a stud adapted to be engaged by said hook and meansengaging the other end of said hook to secure the hook I in place and toretain the stud of the hair spring.

2. In combination with the balance cook or bridge, the hair springconnected theres with and having a stud at one end, a hook mounted inthe balance cock or bridge and adapted to engage the stud carried bythehair spring and means engaging the other end of said hook to secure thehook in place and to retain the stud of the hair spring.

3. In combination with the balance cock or bridge, the hair springconnected therewith and having a stud at one end, a hook adjustablymounted in the balance cook or bridge and adapted to engage the studcarried by the hair spring and means engaging the other end of said hookto secure the hook in place and to retain the stud of the hair spring.

4:. In combination with the balance cook or bridge of a watch ortimepiece, a hair spring mounted in the bridge or cock and carrying astud, means for securing the stud to the balance cock consisting of ahook for engaging the stud, a shank formed with the hook and mounted inthe balance cock or bridge, and an adjusting nut carried by said shankfor adjustably retaining the securing means in place.

In testimony whereof I afiix my signature in presence of two witnesses.
